Component: eyesight camera motherboard failure due to cold weather (code b28b3). Possibly an improper conformal coating that is susceptible to cracking or building moisture which then freezes and cracks components of the camera system. Safety concern: it appears this is common in Subaru eyesight systems for all models years 2017-2019. A local mechanic shop (fairbanks, ak) has seen these systems fail repeatedly in our winter climate. I find this concerning that the system that has the ability to control steering and breaking is susceptible to what we consider normal winter climates. Subaru has been vague on the cause of this issue. Reproduced: yes, this is known and not uncommon per the Subaru dealer service center and an independent local shop. Inspected: yes the vehicle has been inspected by kendall Subaru of fairbanks ak. Warning lights: no warning before failure. Currently the display shows "eyesight" in bold indicating the eyesight system is non functional.
Temperature dropped to -20 and large crack randomly appeared on driver side windshield. This crack has caused the eyesight safety feature to not work meaning I don’t have lane departure warning or forward collision warning. Informed my warranty does not cover the windshield repair or required camera recalibration.
